[W126 Coupe] Do I have suspension problems? (shuddering/instabilityover rougher roads)

[Dawid Loubser]

I typed 16l (l = litres), not 161. :-)

Off topic: As for the new Bugatti Veyron, if you floor it at top  
speed, 161l/100km
may not be so unrealistic :-)

Glad you switched to unleaded!

cheers,
D.
